You added a pixel to the left, which is going to break your image, so get rid of that.

In usenti, instead of just hitting save, try to "save as" and select 16 colors without transparency, that should preserve the palette, though you will need to start with an image that has the palette intact.

Downloaded FEBulider, imported the sprite and it works!Why do I suddenly feel stupid?Also, Leonarth, thanks for the tutorial. It'll really help.Last thing, opinions on the map sprite? Not the second one, though.
